Question

3.
An arbitrary shaped closed coil is made of a wire of length L and a current I ampere is flowing in it. If the
plane of the coil is perpendicular to magnetic field B. the force on the coil is :
1) 2IBL
2) IBL
3) Zero
4) 1B
IBL​

Answer 1

Answer:

2) IBL

Explanation:

sonce F = BIL SinQ

and here Q= 90° ( perpendicular)

hence

F = ILB Sin90°

F=ILB (1)

F= ILb
